"FUJI S2 TIPS & QUIPS" This is going to be an ongoing file of things I have learned on the S2 camera - last update 9/7/03

LENS RESOLUTION TESTING CHART - This chart is a .dwg file that requires an HPGL 24inch plotter and results in a 24 x 36 sheet with lines made to about .001 in. accuracy. This is an ongoing project and the file is constantly evolving. I created the chart to test zoom lenses and evaluate the overall digital camera resolution. If you have ever used the Airforce testing charts, you know what a pain it is to evaluate a lens. This chart simplifies things and allows you to check one lens against another and also to evaluate the camera. Some of the camera CCD algorithms are not the same horizontally as vertically, and this chart can detect the difference. The file plots black lines on white paper. I normally use autocad with black background and reverse the print color. NOTE: this is a VECTOR file. File is "Rez Check Chart MDos.dwg"

LENS/CAMERA FOCUSING CHART - I made this Depth of Field chart to evaluate if the lens was actually focusing where it was supposed to. This again is a .dwg file that requires an accurate HPGL plotter and outputs as a 24 x 36 inch plot. This chart came about as a result of a 150mm Sonnar lens on a Hasselblad that continually focused behind the spot that I saw on the focusing screen. The file plots black lines on white paper. I normally use autocad with black background and reverse the print color. NOTE: this is a VECTOR file.File is "DOF Chart MDos.dwg"

PRINTER CALIBRATION/VERIFICATION CHART - This chart was created to enable me to evaluate what the printer was actually doing. I use this chart to check out how different papers print, and what the effect the different printer settings have on the final print. It is a very useful tool, and is especially useful in testing how black and white print. The chart has an incremental gray scale that corresponds with the gray scale from Photoshop 7.0; RGB color swatches; CMY color swatches; a white with some detail (wedding dress) swatch; and a fleshtone swatch. The image size is 2.6 in. x 4 in. but I usually resize the output print size in photoshop so I can print about 8 tests on on sheet of paper. This 124kb chart can be downloaded by clicking on the thumbnail - right click on the image that comes up and - save as. The same 'tif' file is 2,824 kb. This is the most useful printer evaluation test chart that I have.

PRINTER and LAB CHECKER -This is an 'unretouched' jpg image right from the camera. The image has the contrast range and color balance that I am looking for - so I use it as a 'Lab' test print. I send the image to the lab that I am considering using, and compare it to the print that my printer made. If the image from the camera, looks right on the monitor, and looks right from the printer - I want to find a lab that can print it the same way without me twiddling with the knobs on the monitor to get an acceptable 'lab' print. The 'Donna' jpg file size is reduced to 185 kb for viewing.

CALIBRATION CHART -This is the original calibration chart that I occasionally use to evaluate labs and printers. Sometimes it isdifficult to determine if an image needs a cyan or blue adjustment, red or magenta adjustment - or too much yellow. The MacBeth color checker is helpful because I can pull out the actual chart for comparison. This file "EI_cal_1.jpg" is 285 kb. This file can be downloaded by clicking on the thumbnail - right click on the image - then 'save file as'. The same 'tif' file is 14,654 kb.

COMBINED CALIBRATION CHART - I often use this combined chart that has the gray scale, the RGB, CMY, Fleshtone, White with detail, and unretouched portraits. This chart can reveal subtle aspects of a printer where you know something isn't right, but are not sure what the problem is. The file is "EI_combined_02.jpg" and is 546kb.
